IMPROVEMENT IN CULTIVATO RS.

Specification forming part of Letters Patent No. 49,715, dated September5, 1865.

To all whom it may concern.-

Be it known that I, GEORGE GALKINs, of El Paso, in the county ofWoodford and State of Illinois, have invented a new and usefulImprovement in Cultivators; and I do hereby dc clare that the followingis a full, clear, and exact description of the same, reference being hadto the accompanying drawings and letters and figures marked thereon,which form a part of this specification, and in which Figure 1represents a plan or top view; Fig. 2, a rear elevation and Fig. 3, avertical sectional view of my improved cultivator at the red line 00 inFig. 1.

A is the tongue of the cultivator, and B the frame.

0 is a cross-piece with its ends mortised into the side pieces of theframe.

D D are the cultivator-beams, to which the plow-standards are attached.These beams are attached to the tongue A by means of the bent rods P,which pass through the supports V, (shown in Fig. 3.) The plowbeams areraised and lowered, and also moved sidewise, by the levers E and F.- Thelevers E E have their fulcrums on the cross-piece I, and are so arrangedby means of the rod L, passing through the eye of an eye-bolt driveninto the said cross-piece, that the levers can slide longitudinally. Therod L also fits in the eye of the bolt loosely enough to admit of thelever E being swung laterally, the boltservingas a pivot. The front endsof said levers E are attached to the front ends of the levers F, and thelevers F extend back under the cross-pieces and have their fulcrums inthe supports K, the supports K being attached to the cross-piece (3, andconstructed sufficiently large where the levers K pass through to admitof the ends of the levers receiving both the vertical and lateralmotion. The rear ends of the said levers F are attached to theplow-beams D, as shown. The rear ends of the levers E are connected bymeans of the cross-piece H, and there is also connected thereto theframe'(), with places J J provided therein for the feet of the operator.There is a short lever, M, attached to the cross-piece H and extendingout near the seat, so that the operator, sitting thereon, can operatethe levers E with his hands instead of his feet when he so desires; andthere is also a lever, N, which is attached to the frame 0, with thefront end passing under the staple S, that is driven into thecross-piece O. This lever is so arranged that the operator can operatethe levers E when walking behind the machine. The dis tance between therear ends of the plow-beams D is regulated by the distance between theends of the levers E at the frame 0, and that is regulated by therebeing various holes in the cross-piece H for the bolts that fasten it tothe levers, and by constructing the bottom piece of the frame 0 in twoparts, so that one will slide over the other, thereby allowing the endsof the levers E to be arranged at different distances apart.

It is readily seen that by operating the levers E the plows arecompletely controlledthat is, raised or lowered or thrown sidewise tofollow the sinuosities of the rows.

The frame of the cultivator is raised to adapt it to be used among highcorn by means of the arms T and braces U, which are so constructed as tofirmly support the frame on the wheels, and at the same time avoid thenecessity of using large wheels.

Having thus fully described the use and construction of my invention,what 1 claim, and desire to secure by Letters Patent, is

1. The combination and arrangement of the plow-beams D, levers F,supports K, levers E, provided with the rods L, the cross-piece H, andframe 0, when constructed and operating substantially as and for thepurposes set forth.

2. The combination and arrangement of the plow-beams, levers E and F,provided with their fulcrums, as described, cross-piece H, frame 0, andthe levers M and N, when constructed substantially as and for thepurposes described.
